Is Linux a Unix?
Is Linux a Unix?
Matthew Martin
Camden Rogers
No, Linus didn't buy that UNIX certificate yet. I'd love it if he did though.
Xavier Reyes
linux is a bastardized unix
Jaxon Cox
It imitates Unix, so technically it is Unix-like. On high level, i.e. software it barely diffs from Unix, but on so called "bare metal" level (hardware drivers) are the greatest differences. Disclaimer: not an engineer here, just read it in some book.
Ryan Roberts
You mean GNU/Linux.
Owen Reyes
No, he doesn't
David Flores
did anyone say UNIX?
Justin Flores
on its own it shares absolutely dick with "real" Unix other than the similar way you interact with it
so no
Tyler Rogers
It's Unix-like
Asher Brooks
Gnu's Not Unix.
Aaron Peterson
No it's a kernel duh.
Justin Carter
What's a lunix?
Bentley Fisher
This. It's easier to explain when the proper name is used, since GNU's Not Unix
James Jones
The kernel source code has no heritage from the ATT origin, and purposefully so. Hence, it is not considered "UNIX" and is not encumbered with its commercial license.
Commercial "flavors" like Solaris and HP-UX are descendants of the original ATT code, and are considered UNIX.
Colton Sullivan
no, because it does not conform fully to POSIX sandards
Bentley Ortiz
POSIX is just a meme though. Its random number API for instance is dogshit.
Brandon Thomas
POSIX is the Unix standard. So...
There is a licensing issue: no one pays for Linux to be verified POSIX compliant, so it's not a UNIX.
But it passes every POSIX compliance test as far as I know, so take that for what it's worth.
OSX is a UNIX because they pay for the verification and licensing (and pass). It's worth noting, the Unix portion of OSX is not derived from the original at&t Unix codebase, but from BSD.
I'm pretty sure there are major players out there that are still derived from the actual at&t codebase still, but other than AIX, none spring to mind. HPux, Solaris and irix have been abandoned. I think.
Hudson Powell
Troll harder. Back to /b retard.
Luke Barnes
>it passes every POSIX compliance test
This is absolutely not true
Brody Wright
Which does it fail? I haven't read up about it for some time, but was living under the assumption this was true.
Hudson Hill
Here's the most obvious one

Jayden Rogers
>tfw Linux doesn't stand for Linux is not unix
Luke Harris
To be fair, you can switch the shell and userland binaries. But good point.
Connor Mitchell
You can switch anything. Distros won't be POSIX certified until they actually do that though.
Xavier Wright
GNU /= Linux.
Luis Gutierrez
Nobody said it was you retard.
Linux alone is not an operating system unto itself that can qualify for POSIX certification. We're talking about the entire GNU/Linux operating system
Carson Williams
which only means that the question whether "Linux" is UNIX compliant is ill-posed, all I'm saying. I'm sorry, I know everyone is sick and tired of being bothered with this technicality which honestly bears no practical relevance.
On the other hand, from a GNUser's perspective, full POSIX compliance may be considered exactly that, an ultimately irrelevant technicality.
Colton Powell
It's to Unix what ReactOS is to Windows, basically.
Camden Reyes
>XNU
>X is Not Unix
John Myers
What defines an operating system as UNIX isn't whether or not it has AT&T code in it.
Mason Bell
>GNU (GNU not UNIX)
>Linux (LinusUNIX)
What do you think?
Julian Gomez
no Linux is its own thing and doesnt share any code with unix
Josiah Turner
>LINUX
>Linux Is Not UniX
Benjamin Ortiz
LINUX = Linux Is Not UniX
Carter Ward
GUHNOOS NOT LINUCKS
Carson White
UNIX has nothing to do with heritage, that's Unix. There are multiple UNIX certified Linux OSs
Isaac Richardson
No, it's better.
Henry Cruz
Yes*
Kayden Cox
Guys...I don't understand what POSIX is and I'm sorry for that, but I would like one of you to explain it to me. Is there a Windows equivalent that would help me understand?
Anthony Perry
John Parker
but doesn't that give them more freedom? it doesn't have to conform strictly to a standard.(Although sticking to a standard has its benefits too)
Kevin Ross
no its not. Linux implements POSIX to a certain degree, but thats about it
Robert Johnson
It's basically a "recipe" and a list of specifications an OS must adhere to in order to be declared POSIX compliant. OS X is fully compliant with it, OpenBSD, Linux and Cygwin aren't.
Robert Morgan
Windows has made some attempts at being POSIX compliant.
That's why the hosts file is where it is at C:\Windows\System32\Drivers\etc\hosts.
